SPRING-SEAT GOIQSTBUCTION.

Application filed June 24, 1922. Serial No. 570,644.

This invention relates to the construction of a sprin seat such, for example, as is used in automotive vehicles wherein a framework and a series of coil springs carry suitable padding and an upholstery covering. In the construction of such seats difficulty has been experienced in preventing deformation of the framework particularly the upper border wire directly supporting; the padding and upholstery due to the hard or severe usage which a motor car is frequently called upon to withstand.

An object of this invention is to so brace the framework of such a seat that it shall effectively resist deformation and maintain at all times its original form and shape without any material loss in resiliency.

Another object of this invention is to so connect or secure the bracing members that they will not become detached and injure the upholstery.

Other objects and objects relating to details of construction and economies of manufacture will appear as I proceed with the description of that embodiment of the invention which, for the purposes of the p 'esent application, I have illustrated in the accompanying drawing, in which:

Figure I is a top plan view of the frame and springs of a spring seat back, the padding and upholstery'being removed.

Fig. II is a cross sectional view of the same on the line II-II of Fig. I, and

Fig. III is a fragmentary view corresponding to Fig. I showing the lower halves of two springs and the manner of connecting them with a brace wire.

Similar reference characters refer to the same parts throughout the views and the sectional view is taken looking in the di rection of the small arrows at the ends of the section line.

Referring now to the drawings, a base frame 5 is shown constructed of a pair of longitudinal metal strips 6 and 7 and a series of transverse metal strips 8 secured thereto at their points of intersection by means of tongues 9 struck up from the longitudinal strips and bent over the adjacentedges of the transverse strips. A lower border wire 10 extends about the periphery of the base frame and is secured to the longitudinal and transverse strips by rolling the ends of these strips over the wire. pon this base frame is carried a plurality of cell on thatside of the seat back which is uppermost when the seat is in position are three brace wires 18 secured to the border wire by clips 19. and extending diagonally downward to the longitudinal strip 7 of the base frame to which they are attached by metal clips 20. These brace wires perform an iniportant function in maintaining the border wire in proper form and preventing it from bowing inwardly when the cushion is compressed. To maintain the opposite side of the top border wire in proper form it would be desirable to employ similar means, that is, to connect that side of the top border wire in a similar maner with a portion of the base frame. However, such an arrange ment has been found to be unsatisfactory for the reason that where both sets of hr cs wires are anchored to the base frame some of the brace wires invariably become detached at one end or the other, due to the excessive strains imposed upon them and eventually poke through the padding and the upholstery covering of the seat. To avoid this trouble brace wires 22 connected at one end with the top border wire by means of the clips 23 at the opposite end of the seat, have their opposite ends connected with portions of certain of the coil springs 12, as shown particularly in Fig. II. Connection is made to these springs by means of an anchoring wire 25 extending in a direction longitudinally of the seat and parallel with the base frame, which wire is shown in Figure I, secured to six of the coil springs near their lower portions. Since the springs are ofthe hour glass type, the manner of attaching the anchoring wire 25 to them will be more apparent upon an inspection of Fig. III, as in that view the upper por-- tions of the springs are removed. As shown in that figure the endearing wire 25 is seeured to ens cf the fewer eonvointiens each spring by means of clips 26. To this anchoring wire 25 the brace wires 22 are attached by clips 27.

From the above description and the drawing the operation of this spring seat will be readily apparent. lVhenever the springs are compressed as when pressure is applied to the seat back, the brace wires 18 serve to counteract the inward pull of the springs upon the border wire, and thus maintain that portion of the border frame in proper form. The brace wires 22 function in similar manner respecting the opposite side of the top border frame, but by reason of their being connected to the anchoring wire 25 which may yield due to-its connection with the springs, the brace wires 22 are relieved of undue strain which might cause them to buckle and the attaching clips thereof are saved from being torn loose.

The resiliency of the seat as so constructed is, however, not materially affected since the braces offer no resistance to the compression of the springs.

While I have shown and d'escribed in considerable detail a specific embodiment of my invention it is to be understood that this showing and description is illustrative only and for the purpose of rendering my invention more clearand thatI do not regard the invention-as limited to the details of construction illustrated ordescribed, .nor any of them except'in so far as I have included such limitations within the :terms of the following claims in which it is my intention to claimall novelty inherent in my invention broadly as well as specifically.

hat I claim as new-and desire to secure by Letters Patent is:

1. In a spring seat, the combination of a base frame, a top frame, a plurality of coil springs therebetween, a pair of oppositely inclined braces between said frames, one of which forms a direct connection between the same and the other being connected to the top frame and terminating short of the base frame, and means connecting the latter brace with the springs intermediate their ends.

2. In a spring seat, the combination of a base frame, a top frame, a plurality of springs therebetween, a brace extending diagonally downward from one side of said top frame connected to said base frame in termediate its ends, a second brace extending diagonally downward from the opposite side of said top frame and means for anchoring the lower end of said second brace to one of said springs.

3. In a" spring seat, the combination of a base frame, .a top frame, aplurality of coil springs connected at .opposite ends to said frames, a brace interconnecting said frames extending diagonally from one side of said top frame to said base frame, a member connect-ed to a pluralityof-said springs and extending substantially parallel to said base frame, :and a brace connected to and extending diagonally from the oppositeside of said topframe and connected to said member.

4. In a spring seat, the combination of a base frame, a plurality of coil springs secured thereto, an upper frame comprising a border wire attached .to certain of said springs, diagonalibrace wires connecting said base frame and said border wire at one side of saidseat, an anchoring wire secured to the lower .portionsof certainof said springs, and other diagonal brace wires connecting said anchoring wire and said border wire at the opposite side ofsaid-seat.

In testimony whereof, I-afiix my signature.

HENRY A. VAGNER.
